We study the long-run stochastic stability properties of volunteering strategies in finite populations. We allow for mixed strategies, characterized by the probability that a player may not volunteer. A pairwise comparison of evolutionary strategies shows that the strategy with a lower...

We study how norms can solve distributional conflict inside a clan and the efficient coordination of collective action in a conflict with an external enemy.We characterize a fully non-cooperative equilibrium in a finite game in which a self-enforcing norm coordinates the members on efficient...

We study the residential choice of siblings who are altruistic towards their parents. The first-born child’s location choice influences the behavior of the second-born child and can shift some of the burden of providing care for the parents from one child to the other. These strategic...

We study the effect of size differences for an optimal risk sharing system of intergovernmental transfers in Germany. The German fiscal transfer system should account for the fact that an optimal insurance mechanism has the property that smaller states contribute a smaller share of their tax...

We show how norms can solve the distributional conflict inside a group in an anarchic environment and yield efficient coordination of collective action in a conflict with an external competitor. The equilibrium of the fully non-cooperative game with finite horizon has two interesting features....

When politicians negotiate in international climate conventions they may suffer from incomplete information about each other's preferences about reaching an agreement. As is known, this may cause failure to reach an efficient cooperative agreement. We study the role of the clean development...

We analyze bargaining over international climate agreements in a setting with incomplete information about abatement costs. Unilateral commitment to high abatement reduces the gains from global cooperation. This reduces the probability of reaching efficient international environmental agreements.

This article addresses the challenges of the new security situation that Germany faces against the background of current geopolitical conflicts and the potential weakening of US security guarantees for Europe. The article counteracts the widespread idea that more money and more soldiers are...
